title: [Chronic heart failure in patients with arterial hypertension and ischemic heart desease: age and gender characteristics].
abstract: OBJECTIVE
  to study prevalence of chronic heart failure (CHF) among patients with arterial hypertension (AH) and ischemic heart disease (IHD), and specific features of CHF in patients with different sex and age.
  
  
  METHODS
  We carried out retrospective analysis of CHF prevalence in 2048 patients with AH and/or IHD and prospective study of distribution of clinical hemodynamic variants of CHF in 285 patients with known data of echocardiography and 6-min walk test.
  
  
  CONCLUSIONS
  The prevalence of CHF in our group was 29%, in men it was 2.8 times greater than in women. Most patients with CHF (71%) were older than 60 years. Significant differences were revealed in etiology of CHF between men and women, and between patients of different ages. CHF with EF<45% was diagnosed in 35.8% of patients, Number of patients with EF<45% among men was 5.8 times greater than among women. CHF with preserved EF was found in 64.2% of patients. Purposeful examination of patients with AH and IHD is needed for early detection of CHF.
